How to sort Qt combobox item after removing item from combobox?

NTCYP

Hi,

I have a Comobox in my DialogWindow. I add 3 items in it.

    // TEST DATA LOAD
    ui->comboBoxSQLData->addItem("AAA");
    ui->comboBoxSQLData->addItem("BBB");
    ui->comboBoxSQLData->addItem("CCC");
    QCoreApplication::processEvents();

I also have my connect(SIGNAL/SLOT) for combobox item changed

   // COMBOBOX SELECTION CHANGED
    QObject::connect(ui->comboBoxSQLData, SIGNAL(activated(int)), this, SLOT(handleSelectionChanged(int)));

My combobox item changed function:

void DialogWRITE_CARD::handleSelectionChanged(int index)
{
    // Combobox item text changed
    if(ui->comboBoxSQLData->itemText(index) == "AAA")
    {
        ui->lineEditWrite->setText("AAA");   
    }
    else if(ui->comboBoxSQLData->itemText(index) == "BBB")
    {
        ui->lineEditWrite->setText("BBB);
    }
    else if(ui->comboBoxSQLData->itemText(index) == "CCC")
    {
        ui->lineEditWrite->setText("CCC");   
    }
}

Now I need to remove item first from combobox and than I need to sort item in combobox. How can I do that?

In below function I can remove item from combobox but I dont know how to sort the item?

void DialogWRITE_CARD::on_pushButtonKartYaz_clicked()
{
    // Do something with text
    ………

    int cItem = ui->comboBoxSQLData->count();

    // Remove Current Combobox Index
    if(cItem != 0)
    {
        // Remove Current ComoboBox Item
        ui->comboBoxSQLData->removeItem(ui->comboBoxSQLData->currentIndex());

        // Now Sort the combo box after removing item
        ????????????????
    }
}

Kind Regards

Hi,

I haven't tested but you can use the sort function of the QComboBox's model.

Note that handleSelectionChanged's implementation isn't really optimal. Why not connect comboBoxSQLData's activated(QString)signal on lineEditWrite's setText slot ?

If you remove an element from a sorted list then the list is still sorted. So, do you really need to sort?
